1 Claim. (Cl. 93-36.01)

(Granted under the act of March 3, 1883, as amended April 30, 1928; 3700. G. 757) The invention describcd herein may be manufactured and usedby or for theGovernment for governmental purposes, without the Vpaymentto us of any royalty thereon.

This invention relates to packaging equipment and more particularl tojigs for placing envelope liners in boxes or containers.

The customary Way of lining a box with paper or similar material, or apaper envelope, is to do it by hand. The disadvantage of this method isthat it is slow, inexaot, causes undesirable wrinkling and soiling ofthe paper, and results in unevenness in its placement. This frequentlydefeats its purpose. i

It is an object of this invention to provide a new a'nd improved jig forplacing linings in containers, that Will avoid one or more of thedisadvantages and limitations of the prior art.

Another object of the present invention is to provide a new and improvedjig for lining purposes that will facilitate the placement of the liningin a container, and then to fit same quasiautomatically in a smooth andexpeditious manner.

A further object of the invention is to provide a new and improvedlining jig that Will be simple but effective in structure and operation,capable of manual application and economical to make.

For a better understanding of this invention, and for further objectsthereof, reference is made to the appended drawings and followingdescription, while the scope of the invention is particularly pointedout in the claim.

Referring to the drawings:

Figure 1 is a perspective view showing a lining jig for placement oflinings, embodying this invention, in a container,

Figure 2 shows the lining jig folded and placed in a lining envelope,

Figure 3 shows the lining jig opened in the lining envelope, and

Figure 4 indicates the lining jig opened in a lining envelope placed ina crate, the envelope being partly broken away to show the structuralrelation of the jig in such position.

Similar reference characters refer to similar parts throughout thedrawings.

In the construction shown in the drawings, by way of illustration of theinvention, an envelope lining jig consists of a structure of atriple-section form, somewhat similar to a book cover with two rigidsubstantially planiform backs and flexible junction piece. The threeSections, Ill, II and l2, respectively, are arbitrarily termed left,bottom or base, and right of the framework. The left section or back I 0is of substantially rectangular shape of open skeleton shape so as toleave an opening |3 in its central area. The right section or back |2 isof similar form and symmetrical therewith, with an opening |4 in itscentral area. The bottom section or juncton base consists of two smallfrarnes or base Sections |5 and IE nearly rectangular and of skeletonform with central openings ll and 18 respectively therein, having hingesl9 joining them together, so they can swing together as in Fig. 2, oroutward to lie in a common plane` as in Fig. 1, and hinges 20 forswinging the Sections IO and 42 thereto. The outer hinged sides of theframes l5 and l6 are coextensive with the horizontal bottom sides of thebacks to which they are hinged. Their right ``and left horizontal sideshave the hinges 20 mounted on their inner surfaces, thus joining theframes 15 and |6 to the backs so they can swing straight out 01'collapse towards one another. The frames |5 and IB have their ends 2|-22respectively tapered so that their mutually hinged edges are shortened.The right and left sections have their ends likewise tapered at 23 and24 toward the bottom section ll. The purpose of the taperings is tofacilitate insertion of the folded jig into lining envelope 25, whichnormally is usually folded flat but open at one edge, as indicated inFigure 2. The jig is inserted into the open edge of the envelope afterhaving its two Sections ||l l2 moved into face-to-face engagement, whichalso brings the two frames 15-46 together, as shown in Fig. 2. Thelining or lining envelope 25, with the folded jig in same is placed inan open box, crate or container 26, by hand. Then the operator pushesthe left and right Sections I 0 and l2 downwardly. The bottom wall ofthe box obstructs the straightened or apexedtoggled frames 15 and IS ofthe bottom section, and induces the frames to swing hingedly up flat atright angles to the Sections IO and Il as they are held by the user inthe manipulation of the device. In doing so, the Sections IO and |2,move outwardly in a parallel manner and push the walls of the envelope25 out, into box form, so that the latter fills up against the insidesurfaces of the box 26 and lines it on all sides. The jig may now beremoved while the envelope remains open at the top for the material orarticle to be inserted and covered up by the overlaps of paper. Theproportions of the liner envelope and the boxes are partially Critical,but the jig itself is not necessarily so, as considerable latitude ispermitted, although not necessarily as desirable. This latitude however,permits the jig to be used out any wrinkles that develop, or to removespots or material that may not be desirable therein.

In practice, it is found that the jig Will place linings in containersmany times as fast as the old hand method or make-shifts requirel 'Itdoes a better job, prevents soling and tearing lining'.

It also facilitates the placing` of the article in the box since thelining fits snug'ly against the walls of the box without crumpling andtherefore the full capacity of the box is available for-placernent ofthe article. This is especiallyiimpor-tantwhere the size of a singlearticle is equal to the full ca- .pacityv of the box.V In sucha case, acrumpled venvelope would lprevent the article from fittng vinto'the box.

While there has been described what is at presentconsidered to be a newand improved embodic ment of this invention, it will be noted thatIVarious changes and modifications may be made .thereon withoutdeparting from the, principles 'and spirit of the invention, as soughtto be defined in the following claim.

We claim: A jig for spreaclingavv lining within a container to cause thelining to take substantally the Shape of the interior of the container,comprising first and second thin substantially planiform backs,

a, junction base therebetween, first and second horizontalaxis hingesjoining the bottoms of said backs respectively to opposite sides of saidjunction base, said junction base comprising two substantially identicalSections approximately coextensive in width with said backs at saidfirst and secondhinges, third horizontall axis hinge means 'joining saidsections mutually, each Vofjsaid sections having ends that taperiinwardly in the di- Vrection of said third hinge means, said hingesbeing all dispcsed' on the inner surfaces of the backs andjunction baseSections, the bottoms of Ithe backs and the ends of the said backs andbase section's having smooth bounding edge surfaces, said jig having acollapsed position With said base Sections and said backs face to facein parallel planes and each base section substantially coplanar with itsadjoining back, so that while so collapsed said' jig may be insertedinto a preformed. collapsed lining envelope and saidl backs spreadlaterally apart from each other in said lining. and Vwhereby when saidjunction base contacts the bottom of said liningV envelope and saidSections swing intocoplanar relation substantially at right angles tosaid backs said backs are forced apart and said liner envelope i spreadsubstan- AtiaIJYsm'sOthly againstthe bottom and wallsof the container.
